Lens curvature variable device for changing lens curvature using sensed temperature information

摘要

The present invention relates to a lens curvature changing apparatus for changing the lens curvature by utilizing the sensed temperature information.A lens curvature variable device according to one embodiment of the present invention isAs a lens curvature variable device for changing the curvature of a liquid lens whose curvature varies according to the applied electrical signalLens driving unit for applying electrical signal to liquid lensA sensor section for sensing curvature of a liquid lens formed based on electrical signals andA temperature sensing portion sensing temperature around a liquid lensBased on the sensed curvatureIncludes a control unit for controlling the lens drive to form a target curvature of the liquid lens;Control sectionTo form a target curvatureBased on the sensed temperatureThe changed electric signal is controlled from the lens driving unit to the liquid lens.This makes it possible to quickly and accurately change the curvature of the lens using the sensed temperature information.Diagram
